Application led January 26, 1914. Serial No. 814,488.

T0 all whom 'it may concern Be it known that I, JOHN E. PARRISH, a citizen of the United States, and a resident of Richmond, in the county of Henrico and State of Virginia, have invented an Improvement in Broadcasting Mechanism, of which the following is a specification.

My present invention relates generally to 'broadcasting' machines, and`more particularly to an agricultural machine by which a supply of material may be constantly broadcasted within well defined limits as to direction and extent under control of the operator, the object of my present improvement being to provide a broadcasting mechanism having certain novel features. arranged to permit of the broadcasting* of liquid and powder poisons, and various forms of fertilizer as well as seed of various sizes and kinds. In carrying out these objects, I utilize the construction, arrangement and operation of the various parts shown in the accompanying drawings, which form a part of the specification, and in which- Figure l is a verticallongitudinal section through a' machine including my improved \me`chanism, and taken substantially on line 1 1 of Figs. Fig. 2 is a plan view of the machine. Fig. 3 is a transverse vertical section, taken substantially on line 3-3 of Fig. 2.' Fig. 4L is a detail horizontal section through the broadcasting member. Fig. 5 is a detail vertical` section through the stirring arrangement. Fig. 6 is a detail horizontal section through the cast base of the hopper. Fig. 7 is a plan view of the hopper closing strips. Fig. 8 is a vertical cross section through one of the strips shown in Fig. 7 and taken substantially on line 8-8 of said figure, those parts of the cast base of the hopper immediately surrounding the strip being indicated by dotted lines, and Fig. 9 is a perspective View ofthe feeding hood, the usual operative position of which is shown in dotted lines in Fig. 3. FigflO is a perspective view of the cast base of the A hopper.

Referring now to these figures, the frame generally indicated at A supports a transverse axle B having wheels C and C', wheel C having an integral inwardly facing bev.

eledgear c formed thereon;

'Mounted in and rising from the' frame A,

which is provided with a driver.s seat A and handles kA2, is a forwardly and upwardly inclined 'bracket D preferably formed of cast metal and the lower portion of which is provided with a bearing al through which the shaft B extends, as best shown 1n Fig. 3. The 'frame generally indicated at A as before vstated is also provided with suitable draft means and is detachable from the' shaft B and may be removed with said shaft and a short shaft substituted to connect the bearing d of the bracket D and the wheel C when it is desired to 'use thel broadcasting mechanism as a walking machine. Hence the handles A2 areprovided and the upper forward portion of the bracket-D has a vertical series of apertures d to which draft connections may be had.

' The bracket D is important for the above reasons and due further to the fact that it is provided with a rearwardly extending port-ion in the form of a circular frame D upon which the grooved upper outer edge of the cast hopper base E is revolubly seated, these parts being located above the wheel C and axle B and the hopper base E having a central lower bearing e loosely journaled upon the upper end portion of a vertical shaft F, the lower end of which has a splined beveled gear if normally in engagement with the integral gear c of t-he wheel C. rIhis beveled gear f is held in position by a spring f', against the tension of which it may be moved out of Contact with gear c through the use of, a lever G extending beneath gear f, said lever being pivoted at its forward end upon the lower portion of the bracket D and having an upwardly projecting rod G connected to its rear end, whereby it may be raised to disengage the gears when desired, all as best shown in Fig. l.

Disposed upon the vertical shaft F below the cast hopper base E is a broadcasting member H, consisting of a conical base 7L to which is secured a central bearing having transverse apertures h2 which may be secured to the shaft F by a transverse pin h3.

The broadcasting member H also has a plurality of curved tangential vanes H', and

in practice is rotated by shaft F so that any material disposed between the several vanes H ywill be thrown outwardly due to the centrifugal motion of the member and in an upward direction due to the conical base t thereof. Adjacent their outer ends the vanes H are increased in height and are connected by an upper vcircular strip H2, bracing these series ot vanes H and serving fto form a supportfor the feeding hood l,

shown in detail in Fig. 9 and indicated by dotted lines in Fig. 3.

The strip H2 and the conical base of they broadcast-ing member are provided with series of apertures, the apertures of the base being indicated at h4 in- Fig. d, so thatthe body `of the hood l, in the form of a circular strip t havin apertures i', may be secured upon either t e strip H2 or the base h with its flanged portion T projecting downwardly and upwardly in the two positions respectively.

llt will be noted that the danged portion l of the hood ll is transversely slitted around its circumference, and that there are thus formed a circular` series of tree tongues, which may be readily bent to any desired angleand the dedection of the material from the broadcasting member thus controlled.` By the use of the hood secured upon the plate H2 as seen in dotted lines in Fi 3, the

material from the broadcasting mem erwill be deflected in a downward direction and liquid.

prevented from spreading beyond t-he extent desired and controlled by bendin the several tongues of the Harige lto t e proper position. The same is true when this position of the hood is reversed, and itis securedv to the base it of the broadcasting member except that in this osition the material will be thrown upward y beneath the upper high grown plants. This is particularly desirable in connection with the application of vermin destroying poisons, either powdered or'- The hopper 'E' in which thematerial is initially introduced is in the form of an inverted cone, the lower truncated end ofwhich is disposed within land secured to the upper outwardly Haring portion ot'the cast base E before mentioned, and communicates freely with ,the interior of this cast base, the latter having aconical base e and having its wall cut away in order to rovide a feed slot e2 above the base e an extending for a -distance slightly over one half the circumference ,of said base, asl will best be seen by reference to Fig.- 6. Thus lthe material is normally fed through the slot e2 and onto the distributing member H, the latter` promptly broadcasting it so that the direc-4 tion in which the material is thrown may be controlled by circular adjustment of the.

hopper E and its base E, which are freely disposed upon the circular portion Df of the bracket D, as before described.- With the,

parts inthe position shown in Figs. 3 and i, the material will -be broadcast Aover a semi- 'as desired.`

incassa circulararea either to the right, left or rear The wall of the cast hopper base E above l its feed slot e2 and also the conical base e have vertical apertures e8 for the reception of pins e adapted to pass also throu h su plemental closure members E2 and 2t e i'ormer being somewhat elongated so as to close the feed slot e2 except for small spaces at oppositel sides. When the closure strip E2 is in position, as indicated in dotted lines in Fig. 6, the material is fed from the hopper base through two small feed openings at diametrically opposite points and is consequently broadcast from member H in diametrically opposite directions which, with the hood l in use and in the position shown in dotted lines in Fig. 3, permits seed, fertilizer orpoison to be drilled along spaced lines the' width owhich will depend upon the inclination of the tongues of the Harige l of the lhood.' ln like manner the other and shorter closure strip E3. may be connected withinl the wall of the hopper baseto close the small feed space at one side when material is to be drilled in a single line.

' The amount of material to be fed may he conveniently controlled by a band J encircling the wall of the cast hopper base F, as best shown inFig. 3, and movable vertically thereon, to a positionl partially or wholly covering the feed slot e2, by means of a lever il intermediately pivotedon a portion of the Abracket-D and having a oke at its iorward end, the extremities 4o which engage trunnions j projecting from the sides of the controlling band .,lf;

The upper extremity of the shaft F isv ver,

`tcally bored to form a space f2 for holding lubricant and is provided with a set screw f3 threaded into the end of the 'bore and a' lateral openin ft communicating with said bore and by w ich the lubricant/is fed tothe bearing 'e of the hopper base. This ex tremity of theshait F,as best shown in Fig. 5, is also provided withl a head K se' cured thereon by set screws k and provided with outwardly projectingy stirring arms K projecting wit in the cast hopper base E to` constantly agitate the materialtherein during use, the head K beingprotected by a cap K2. Thus it is simply necessarytc release set screw c in order that the stirring head K may be removed and provide for the removal. of the hopper and its cast base and also of the broadcasting member H.

Thus from the foregoing itis believed that the advantages of my improved broadcasting mechanism may be clearlyl understood and readily appreciated, either in connection with various forms offertilizer and liquid or powdered vermin destroying poia su porting bracket havin a portion extending horizontally above t e broadcasting member and in the form of a ring, and a feed hopper having its base extending down` wardly through the ring and provided -with a slotted opening in its side wall to deliver material upo/nfthe broadcasting member, and also provided with` a grooved upper edge loosely seated upon the said ring of the bracket whereby the hopper and its base may be freely rotated in order to control the direction in which the material is thrown.
